Motivation: Adding an example that showcases Netty’s HTTP/2 codec and that is slightly more complex than the existing hello-world example. It is based on the Gopher tiles example available here: https://http2.golang.org/gophertiles?latency=0 Modifications: Moved current http2 example to http2/helloworld. Added http2 tiles example under http2/tiles. Result: A Netty tiles example is available.
